在很真核细胞的种类，配对的三基本的步，再结合和联会发生在成熟分裂的前期期间我。相应 chromosomal 配对和再结合为染色体的精确分离是必要的。与象再结合和联会那样的学习得好的过程相对照，染色体配对的许多方面仍然是阴暗的。在几种的最近的进步显示 telomere 花束形成能便于相应染色体由把染色体结束带进靠近的最近配对，但是聚类的 telomere 的唯一的存在不为认出相应的对是足够的。在另一方面，到后代的从父母的基因材料的精确分离在成熟分裂期间依赖于在 reductional meiotic 部门( MI )的相当或相同的事物的分离，从一样的杆单音取向的姐妹 kinetochores 展出，并且姐妹染色单体的分离从二杆在有 kinetochores 的方程式的 meiotic 部门( MII )期间显示出双性人取向。取向和分离的内在的机制仍然是不清楚的。这里，我们在提供染色体怎么发现他们的搭挡和机制调停 chromosomal 分离的卓见的植物和另外的种类集中于最近的研究。

英文摘要：

In most eukaryotic species, three basic steps of pairing, recombination and synapsis occur during prophase of meiosis I. Homologous chromosomal pairing and recombination are essential for accurate segregation of chromosomes. In contrast to the well-studied processes such as recombination and synapsis, many aspects of chromosome pairing are still obscure. Recent progress in several species indicates that the telomere bouquet formation can facilitate homologous chromosome pairing by bringing chromosome ends into close proximity, but the sole presence of telomere clustering is not sufficient for recognizing homologous pairs. On the other hand, accurate segregation of the genetic material from parent to offspring during meiosis is dependent on the segregation of homologs in the reductional meiotic division （MI） with sister kinetochores exhibiting mono-orientation from the same pole, and the segregation of sister chromatids during the equational meiotic division （MII） with kinetochores showing bi-orientation from the two poles. The underlying mechanism of orientation and segregation is still unclear. Here we focus on recent studies in plants and other species that provide insight into how chromosomes find their partners and mechanisms mediating chromosomal segregation.
